调用所有匹配的第三应用：

[java]view plaincopy 
   
 publicclassAppFilterActivityextendsActivity 
 { 
 @Override 
 publicvoidonCreate(BundlesavedInstanceState) 
 { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.main); 
  
 Intentintent=newIntent(Intent.ACTION_ATTACH_DATA); 
 intent.setType("image/png"); 
  
 IntentchooserIntent=Intent.createChooser(intent,"Selectapp"); 
 if(chooserIntent==null) 
 { 
 return; 
 } 
 startActivity(chooserIntent); 
 } 
 } 

过滤app列表中的某个app:

[java]view plaincopy 
   
 publicclassAppFilterActivityextendsActivity 
 { 
 @Override 
 publicvoidonCreate(BundlesavedInstanceState) 
 { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.main); 
  
 Intentintent=newIntent(Intent.ACTION_ATTACH_DATA); 
 intent.setType("image/png"); 
  
 showSetAsList(intent); 
 } 
  
 privatevoidshowSetAsList(Intentintent) 
 { 
 PackageManagermPackageManager=AppFilterActivity.this.getPackageManager(); 
 List<ResolveInfo>mShareAppLst=mPackageManager.queryIntentActivities(intent,0); 
 List<ResolveInfo>mAppLst=newArrayList<ResolveInfo>(); 
 intnumActivities=mShareAppLst.size(); 
 //遍历设置为列表，移除设置为列表中的联系人 
 for(inti=0;i<numActivities;i++) 
 { 
 ResolveInforeinfo=mShareAppLst.get(i); 
 if(reinfo.activityInfo.name.equals("com.android.contacts.activities.AttachPhotoActivity")) 
 { 
 continue; 
 } 
 mAppLst.add(reinfo); 
 } 
 ChooseAppAdaptermAdapter=newChooseAppAdapter(mAppLst,AppFilterActivity.this.getApplicationContext()); 
 AlertDialog.BuilderalertDialog=newAlertDialog.Builder(AppFilterActivity.this); 
 alertDialog.setTitle("selectapp"); 
 alertDialog.setAdapter(mAdapter,newShareAppItemClickListener(intent,mAppLst,mAdapter)).create().show(); 
  
 } 
  
 publicclassChooseAppAdapterextendsBaseAdapter 
 { 
 privateList<ResolveInfo>mDialogList=null; 
 privatePackageManagermPackageManager=null; 
 privateLayoutInflatermInflater=null; 
  
 publicChooseAppAdapter(List<ResolveInfo>mDialogList,Contextcontext) 
 { 
 this.mDialogList=mDialogList; 
 this.mPackageManager=context.getPackageManager(); 
 sort(); 
 mInflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
 } 
  
 @Override 
 publicintgetCount() 
 { 
 returnmDialogList!=null?mDialogList.size():0; 
 } 
  
 @Override 
 publicObjectgetItem(intposition) 
 { 
 returnposition; 
 } 
  
 @Override 
 publiclonggetItemId(intposition) 
 { 
 returnposition; 
 } 
  
 @Override 
 publicViewgetView(intposition,ViewconvertView,ViewGroupparent) 
 { 
 if(position>=mDialogList.size()) 
 { 
 returnnull; 
 } 
 Viewview; 
 if(convertView==null) 
 { 
 view=mInflater.inflate(R.layout.share_menu_item,parent,false); 
 }else 
 { 
 view=convertView; 
 } 
 ImageViewcategoryIcon=(ImageView)view.findViewById(R.id.menu_icon); 
 categoryIcon.setImageDrawable(((ResolveInfo)mDialogList.get(position)).loadIcon(mPackageManager)); 
 TextViewcategoryName=(TextView)view.findViewById(R.id.menu_title); 
 categoryName.setText(((ResolveInfo)mDialogList.get(position)).loadLabel(mPackageManager)); 
 returnview; 
 } 
  
 publicvoidreleaseData() 
 { 
 mDialogList.clear(); 
 mPackageManager=null; 
 mInflater=null; 
 } 
  
 publicvoidsort() 
 { 
 if(getCount()>1) 
 { 
 ResolveInfo.DisplayNameComparatorrComparator=newResolveInfo.DisplayNameComparator(mPackageManager); 
 Collections.sort(mDialogList,rComparator); 
 } 
 } 
 } 
  
 publicclassShareAppItemClickListenerimplementsDialogInterface.OnClickListener 
 { 
 Intentintent=null; 
 List<ResolveInfo>mShareAppLst=null; 
 ChooseAppAdaptermAdapter=null; 
  
 publicShareAppItemClickListener(Intentintent,List<ResolveInfo>mShareAppLst,ChooseAppAdaptermAdapter) 
 { 
 this.intent=intent; 
 this.mShareAppLst=mShareAppLst; 
 this.mAdapter=mAdapter; 
 } 
  
 @Override 
 publicvoidonClick(DialogInterfacedialog,intwhich) 
 { 
 IntentresolvedIntent=newIntent(intent); 
 ResolveInfoinfo=mShareAppLst.get(which); 
 ActivityInfoai=info.activityInfo; 
 resolvedIntent.setComponent(newComponentName(ai.applicationInfo.packageName,ai.name)); 
  
 try 
 { 
 startActivity(resolvedIntent); 
 }catch(Exceptionex) 
 { 
 ex.printStackTrace(); 
 } 
 releaseData(); 
 } 
  
 publicvoidreleaseData() 
 { 
 intent=null; 
 mShareAppLst.clear(); 
 mAdapter.releaseData(); 
 } 
 } 
 } 

2, share_menu_item.xml
